IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Patent No. 211,497, dated January 21, 1879 application ilcd August 16, 187e.

To all 'whom it may concern:

Be it known that I, JOHN O. CRAWFORD, of Douglass, in the county of Fayette and State of Iowa, have invented a new and useful Improvement in lVa-shing-Machines, which improvement is fully set forth in the following specification and accompanyingdrawing.

The invention relates to an improvement in the construction of a washing-machine 5 and consists of an oblong box with a portion of the bottom plane, and sloping downward at each end, and the central portion concave, with V-shaped parallel grooves running across it, formed either of wood or sheet metal, crimped similar to a common wash-board. A semi-cylindrical rubber, with its convex side grooved like the curved surface of the bottom, works in slots in the side of the box.

Referring to the drawings, Figure 1 represents a perspective view, and Fig. 2a sectional longitudinal view through the center.

Ais an oblong box supported on legs, having at each end, at B, a portion of the bottom inclined downward, and in the center curved and provided with V-shapcd grooves O, formed of sheet metal or wood.

A semi-cylindrical rubber, D, having at each end a journal, F, which tits loosely in slots in the sides of the box A, has upon its convex surface V-shaped grooves similar to those on the bottom. Uprights G are at-tached to each end of the rubber D, and have arms H attached to them at right angles.

Between the ends of arms H rods I are attaehed, forming handles for working the machine, and giving a means of applying pressure while operating.

The clothes to be washed are placed between the concave bottom and the rubber, and by means of the handles the rubber is rocked to and fro, and at the same time it can be pressed down by the operator, if so desired.

The open spaces'at each end of the machine allow the clothes at each motion of the rubber to become loosened up and soaked with water, and at the same time the inclination of said ends toward the center of the suds-box causes the clothes to continuallyT move toward and under the rubber for its repeated actionan important and valuable feature of my invention.

What I claim is- A washing-machine having the central portion oi' its bottom curved and provided with ribs O, and having the ends B of said bottom inclined toward its curved portion, in combi; nation with a semi-cylindrical rubber having ribs E, uprights Gr, cross-bars H, and handles I, substantially as shownand described.
